1Introduction
This document defines EP06 module, and describes its air interface and hardware interfaces which are
connected with customers’ applications.
This document can help customers to quickly understand the interface specifications, electrical and
mechanical details, as well as other related information of EP06 module. To facilitate its application in
different fields, reference design is also provided for customers’ reference. Associated with application
note and user guide, customers can use the module to design and set up mobile applications easily.
1.1. Safety Information
The following safety precautions must be observed during all phases of the operation, such as usage,
service or repair of any cellular terminal or mobile incorporating EP06. Manufacturers of the cellular
terminal should send the following safety information to users and operating personnel, and incorporate
these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for
customers’ failure to comply with these precautions.
Full attention must be given to driving at all times in order to reduce the risk of an
accident. Using a mobile while driving (even with a handsfree kit) causes
distraction and can lead to an accident. You must comply with laws and regulations
restricting the use of wireless devices while driving.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is
switched off. The operation of wireless appliances in an aircraft is forbidden, so as
to prevent interference with communication systems. Consult the airline staff about
the use of wireless devices on boarding the aircraft, if your device offers an
Airplane Mode which must be enabled prior to boarding an aircraft.
Switch off your wireless device when in hospitals, clinics or other health care
facilities. These requests are designed to prevent possible interference with
sensitive medical equipment.

6/ 50
Please do not discard. Maybe wireless devices have an impact on the environment
so please do not arbitrarily discarded.
Cellular terminals or mobiles operating over radio frequency signal and cellular
network cannot be guaranteed to connect in all conditions, for example no mobile
fee or with an invalid (U)SIM card. While you are in this condition and need
emergent help, please remember using emergency call. In order to make or
receive a call, the cellular terminal or mobile must be switched on and in a service
area with adequate cellular signal strength.
Your cellular terminal or mobile contains a transmitter and receiver. When it is ON,
it receives and transmits radio frequency energy. RF interference can occur if it is
used close to TV set, radio, computer or other electric equipment.
In locations with potentially explosive atmospheres, obey all posted signs to turn
off wireless devices such as your phone or other cellular terminals. Areas with
potentially explosive atmospheres includefuelling areas, below decks on boats,
fuel or chemical transfer or storage facilities, areas where the air contains
chemicals or particles such as grain, dust or metal powders, etc.

Figure 4: Reference Circuit of (U)SIM Card Interface with a 6-pin (U)SIM Card Connector
In order to enhance the reliability and availability of the (U)SIM card in customers’ application, please
follow the criteria below in (U)SIM circuit design:
Keep layout of (U)SIM card as close to the module as possible. Keep the trace length as less than
200mm as possible.
Keep (U)SIM card signal away from RF and power supply traces.
Keep the trace width of ground and USIM_VDD no less than 0.5mm to maintain the same electric
potential. The decouple capacitor of USIM_VDD should be less than 1uF and must near to (U)SIM
card connector.
To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away from each other and
shield them with surrounded ground.
In order to offer good ESD protection, it is recommended to add a TVS whose parasitic capacitance
should not be more than 50pF. The 22 ohm resistors should be added in series between the module
and the (U)SIM card so as to suppress EMI spurious transmission and enhance ESD protection.
Please note that the (U)SIM peripheral circuit should be close to the (U)SIM card connector.
The pull-up resistor on USIM_DATA line can improve anti-jamming capability when long layout trace
and sensitive occasion are applied, and should be placed close to the (U)SIM card connector.

EP06 is compliant with USB 2.0 and USB 3.0 specifications. Meanwhile, The USB 2.0 interface supports
high speed (480Mbps) mode and full speed (12Mbps) mode. It is used for AT command communication,
data transmission, GNSS NMEA output, software debugging, firmware upgrade and voice over USB2.0*.
The data rate of USB 3.0 interface is up to 5Gbps, and it is used for AT command communication, data
transmission, GNSS NMEA output and voice over USB 3.0*. The following figure shows a reference
circuit of USB 2.0&3.0 interfaces.

In order to ensure the integrity of USB 2.0&3.0 data line signal, R1, R2, C1 and C2 components must be
placed close to the module, C3 and C4 components must be placed close to the MCU, and also these
components should be placed close to each other.
In order to ensure the USB 2.0&3.0 interface design corresponding with the USB 2.0&3.0 specifications,
please comply with the following principles:
